The adhesion was not perfect....bummer!!!! I can scrap it off if I press really hard on it with my tough fingernail. The ink does not flake off. The silnylon can be rolled ito a ball tightly and has no effect on the ink. Under normal handling of a tarp printed with the ink all should be well.

I picked up a new product that seems to be the kind of thing needed to increase adhesion. I tested it on sil and it removed the silicone from the surface. I used a cotton swab to wash a small spot with it. Now on that spot water "plates out" no beading of water droplets. Now I need a small syringe to measure accurately. Where do I get one locally, Walgreens?
